b all whom it may concern;

Be'it known the i, Enronrrr l rnisori, 'i izen of the United residing eiletue, in the county of. Allegheny and .5 of'Pennsylvania, 15H? invented certain w and useful improvements in Metal Window-Frames; and I do declare the fol-- lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apperns to make and use the same, reference r and to the letters and figurwhich form at part of this specification.

My invention relates to a new and useful improvement in metal window frames, the mary object being to provide a device of ie churacterbefore mentioned that will be proof, simple in construction, and prec- "icully inexpensive of manufacture.

The construction set forth in the following 7 cification is intended to be used in cons nection with the device shown and desc 'ibed in my application filed November 2d, 1906, Eaerial No. 341,729 for metal. window sash With the above objects in View my 1 tion further consists of the novel COHSLZUC" tion and arrangement of parts, as will. be more fully described in detail, reference being had to the accompanying drawing in which Fi ure 1 is a side elevation partly in sec b relative position of the sashes with respect to the jamb and frame. Fig, 2 is a sectional top plan View of one side of the jamb showing sashes seated therein.

Throughout the drawing corresponding numerals of reference denote like parts, in whiclrl designates the upper or head portion of the window frame, which may be constructed as shown, or any other suitable configuration may be substituted. This aforesaid section of the frame can be formed from one sheet of metal bent or pressed as shown, and joined at any suitable point, or it may be constructed of a plurality of sec tions likewise joined together. The inside face of this upper portion is designated by the numeral 2 and the outer face by the numeral 3. The lower or sill portion of the f ame, designated by the numeral 4, is bent or pressed so as to provide, suitable inclined bearing surfaces for the sash portlonsi The side sect1ons;or gamb 5 of the frame upper and lower ng had to the accompanying drawins! es of refe ici in which i su; ended the weights 6 6 we nlce'wise (1 similar mar ne to the head The fr ends of this i. necte by one or A- cured by bolts if" i y Li means The r formed ends of this jitlflj scribed efiords a ready means for getting at the securing bolts 12 and also PIO'HQGS 2L space for the nClil'lISSlOll suing bending the fully dc the jam-b wed by any suitable first" is an glad i ction or pulley stile 13 which is prefe constructed in two sec- .tions an upper and lower nie-mben the same eing l'tll'lOl abl from their normal positions in the jamb to facilitate getting at the sash weights. Sufficient clearance only is left between the ends 5' of the jamb and ends of said pulley stile 13 fdr the admit tance and play of a guide portion or flange 14: formed in the sides of each sash. The central portion of said pulley stile is formed at 15 with a U shaped conformation, whose two sash members. The sides of this pulley to provide it single contacting edge for engagement with the sash portions.

Arranged between the sides of each sash and the pulley stile is an angled weather strip 16 which extends'the full length of said'sash, This member is intended to 0p crate pp and down with the movement of the sash but is carried and secured thereto in such a way that it will be in constant en gagement with the pulley stile 13, being lion as above desides provide guide bearing surfaces for the a made to corn n in cross s so figuration of the top 7 side sections or jambs i. are preferably formed with a flange portion- 7 which is ntended as a locking means to enter the masonry and aid in holding thesejumb o5 tions firmly in position. A partition i is likewi provided aboutniidway betuecn the sidewa of the janib, which poi-fol fui'iction of separating the i 'ghts The two end portions 5 of the 5 id. 70 which determine the width in of the two sashes and 10 inc into space, are preferably bent in a Z forimi ion or in other words bavii two he sent v id parallel fl nges connet d by an acute an lei 1 s to the said braces stile are also bent to a Z formation in order clude air and dust from entering the room '10 at the sides of the window and also prevent rattling. 6 Suitable openings 18 are provided in the upper portion of the pulley stile through which project the sash pulleys 19 suitably supported in any well known manner. 'It will be. observed that in this invention less friction will be encountered between the sashes and pulley stile than was shown and described in mylprevious application, referred to in the beginning of this specification, by reason of the arrangement of said pulley stile with respect to the limiting ends of the jamb portion 5'. This feature will be appreciated by those familiar with'the art as affording a means for more easily raising and lowering the sashes.

An inverted V shaped recess 20 is provided on the under side of the head portion 1 for the purpose of-receiving a lip or flange 21 formed on the top rail of the outside sash 10. This arrangement acts as a retardantto any dust or air entering the room at that meeting point.

The lower or inside sash is herewith shown provided on its upper meeting rail with a projecting spring portion 22 which is designed to closely engage an upwardly extending flange 23 formed on the lower or meeting rail of the upper sash. This arranigement is intended for the purpose of uding air or dust at that point. A spring contacting portion 24; provided on the bottom rail of the lower sash, which engages against the sill portion 4, will exclude air and dust at that point.

Having thus fully shown and described my invention what I claim as new, and de-. sire to secure by Letters Patent is:

1. In a window frame the combination of a hollow metallic j amb, the free limiting ends of which are bent in a Z formation and joined together by suitable-brace members, of a pulley stile seated between said limiting ends having a central guide and end bearing portions for engagement with the sides of the operating sashes.

2. In a window frame in which are mounted two sashes, the combination of a hollow metallic jamb whose free ends are bent in a Z formation and limit the width in cross section of the two sashes, of suitable brace members secured to and uniting the two ends of said jamb, and a removable pulley stile seated between the ends of said jamb,
